ViewPager在滚动型 [英] ViewPager in ScrollView

问题描述

我需要有一个ViewPager内的滚动型，但ViewPager只是当它在滚动型，一切都很好，当我不使用滚动型不会出现。

我已经看到了这样的被问这里的计算器或其他网站上，所有的人都已经回答了你必须把 Android的几个问题：fillViewport =真正的你的滚动视图来解决这个问题，但对我这个解决方案行不通，ViewPager仍然没有，即使我有出现安卓fillViewport =真正的在我滚动视图。

我想的东西得到了在Android的API或东西，这个解决方案行不通了改变，没有人知道我怎么可能作出viewpager出现在滚动视图？

更新：一个工作滚动型布局XML：

 ＆LT;滚动型
    机器人：ID =@ + ID / scrollView1
    机器人：layout_width =FILL_PARENT
    机器人：layout_height =FILL_PARENT
    机器人：fillViewport =真正的＆GT;


    ＆LT;的LinearLayout
        机器人：ID =@ + ID / linearLayout1
        机器人：layout_width =FILL_PARENT
        机器人：layout_height =FILL_PARENT
        机器人：方向=垂直＆GT;

            ＆LT; android.support.v4.view.ViewPager
                机器人：ID =@ + ID / itemsViewPager2
                机器人：layout_width =FILL_PARENT
                机器人：layout_height =WRAP_CONTENT＆GT;
            ＆LT; /android.support.v4.view.ViewPager>
    ＆LT; / LinearLayout中＆GT;
 ＆LT; /滚动型＆GT;
 

解决方案

我跑进了过去类似的问题。 A查看，传呼机必须有一组高（它不能完成内容）。由于ViewPager加载单独的页面，而不是一次全部，就不会知道什么是总结的内容，其实就是。设置layout_height到FILL_PARENT或一组DP允许ViewPager静态地设置它的高度和其他布局内的反应更相应。

I need to have a ViewPager inside a ScrollView but ViewPager just does not appear when its in ScrollView, everything is ok when i dont use ScrollView.

I've seen a couple questions like this being asked here on stackoverflow or on other sites and all of them have been answered that you have to put android:fillViewport="true" to your scrollview to fix the problem, but this solution doesnt work for me, ViewPager still does not appear even if i have android:fillViewport="true" in my scrollview.

I guess something got changed in the android api's or something and this solution doesnt work anymore, does anyone know how i could possibly make a viewpager appear in a scrollview?

UPDATE: A working ScrollView layout XML:

<ScrollView
    android:id="@+id/scrollView1"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:fillViewport="true">


    <LinearLayout
        android:id="@+id/linearLayout1"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:orientation="vertical">

            <android.support.v4.view.ViewPager
                android:id="@+id/itemsViewPager2"
                android:layout_width="fill_parent"
                android:layout_height="wrap_content" >
            </android.support.v4.view.ViewPager>
    </LinearLayout>
 </ScrollView>

解决方案

I ran into a similar problem in the past. A View-Pager must have a set height (it cannot wrap-content). Since a ViewPager loads separate pages, and not all at once, it won't know what 'wrap-content' actually means. Setting the layout_height to fill_parent or a set dp allows the ViewPager to statically set it's height and react more accordingly within other layouts.
